Title: Improvements in or relating to the draught control in stoves, boilers and like heating apparatus
IPC: F23N3/00
Filed: 1932-08-20
Abstract: 406,271. Regulating draught in stoves. BELL'S HEAT APPLIANCES, Ltd., NAPIER, J. K., and SCOTT, C. L., 157, Queen Victoria Street, London. Aug. 20, 1932, No. 23401. [Class 126.] In a stove, boiler, &c., particularly one having accurate air supply control, e.g. by means of a thermostat, the ash-pit door and a spoil-draught damper are connected so that opening of the ash-pit door results in opening of the damper to spoil the draught, the damper being closed automatically to restore the draught when the ash-pit door is closed. Alternatively, the ash-pit door catch and a spoil-draught damper are interconnected for the same purpose. As shown in Fig. 5, the rod 20, which is pressed outwardly by a spring 23, is connected by an intermediately pivoted lever, a rod 27, a bell crank lever 28, a rod 29 and an arm 30 to a spoil-draught damper 32. When the door 2 is closed, a projection 19 on it presses the rod 20 inwards against the spring 23, and so holds the damper 32 so as to close the spoil-draught channel 34. When the door is opened, the rod 20 is pressed outwardly and the damper 32 moved to open the channel 34. In the alternative, shown in Fig. 2, the door catch 6 is mounted on a spindle 15 carrying an arm 14 coupled by a rod 13 and arm 12 to the spindle of the damper 10, which is urged towards the closed position by the spring 11. Stops limit the rotation of the catch. The door may be positively coupled to the damper, and the connection between the door and damper may be adjustable.

Title: Method and apparatus for the detection of a component in a gas
IPC: G01N21/86
Filed: 1965-06-02
Abstract: 1,100,810. Photo-electric gas monitoring. RESEARCH APPLIANCE CO. June 2, 1965 [June 3, 1964], No. 23586/65. Heading G1A. A gaseous or particulate component of a gas is detected by passing the gas through a test area of a tape which darkens either due to chemical reaction of the gaseous component with the tape or on the other hand due to deposition of the particles. The darkening of the tape is sensed photo-electrically and upon reaching a predetermined value causes the tape to be shifted to expose a fresh test area to the gas 3; if the predetermined level is reached within a predetermined time, thereby indicating an undesirable concentration of the component an alarm is additionally sounded. In the embodiment shown in Fig. 4, a gas stream containing hydrogen sulphide enters at tube 57, passes through a lead acetate tape 15, and exhausts via tube 56. The tape is forced against a sealing ring 47 by a lower ring 49 for the period of the test and upon the light falling on photo-cell 54 reaching a predetermined value, the solenoid 59 is operated to lower the ring 49 and permit the tape to be advanced. For each fresh test area before the period of the test begins and before there is any detectable darkening by the gas. The instrument is automatically calibrated by adjusting the intensity of the lamp until the detector output has a standard value, thereby compensating for variations in the opacity of the tape.

Title: Electrodes for galvanic cells
IPC: H01M4/62
Filed: 1974-05-28
Abstract: 1468591 Electrode containing nickel or iron as conducting material DEUTSCHE AUTOMOBIL GmbH 28 May 1974 [1 June 1973] 23638/74 Heading H1B [Also in Division C7] An electrode comprises either an active mass or an electro-catalyst, an organic binding agent and a conductive substance, wherein the conductive substance consists of a voluminous material obtained by thermal decomposition of nickel carbonyl and/or iron carbonyl in the presence of an unpreheated inert gas. The nickel or iron conductive substance comprises a masslike structure of felted crystals grown on to one another in the form of threads. In one example for making a nickel hydroxide electrode, nickel tetracarbonyl was evaporated by heating to 70 C. and the resulting vapour was mixed with unheated nitrogen in a volume ratio 1 : 20. The gas mixture was supplied to a quartz tube heated at 400 C. when the carbonyl was thermally decomposed and the moss-like voluminous nickel material was formed on the tube walls. This material was removed from the tube and disintegrated in a knife mill and mixed with Ni(OH) 2  and polyisobutylene, the pulverous mixture being pressed on to a nickel screen serving as a current collector. In another example for making an air electrode, nickel made as in the previous example was mixed with manganese oxide catalyst and PTFE and the mixture pressed on to a nickel screen. One side of the electrode was then made hydrophobic by coating with PTFE, the PTFE afterwards being sintered. In a further example for making an iron electrode, iron pentacarbonyl was vaporized and mixed with unheated argon in a volume ratio 1 : 25, the mixture being supplied to a quartz tube heated at 450 C. After the thermal decomposition the voluminous iron product was tempered at 500 C. in an argon atmosphere and disintegrated. The iron conductive substance was mixed with magnetite and polystyrene and the mixture dissolved in benzene was pasted on to a sheet of iron wire fleece serving as current collector. Finally, the benzine was evaporated and the electrode was compressed. When making a conductive substance for an iron electrode, a mixture of iron carbonyl and nickel carbonyl may be used; moreover, the active mass in the iron electrode may be Fe 3 O 4 . In another example the active mass is cobalt.

Title: Method and means for making threads, cords and tapes of vitreous material
IPC: C03B37/02
Filed: 1936-09-05
Abstract: 481,126. Making glass threads. POLLOCK, S. A. Sept. 5, 1936, No. 24333. [Class 56] A method of making threads or tapes of vitreous material, such as glass, consists in drawing fibres from a viscous mass of the material and stranding the fibres simultaneously with the drawing. Glass batch or molten glass is placed in a crucible 3 which is heated electrically and is surrounded by a refractory tube 2 and with a heating-element that supplies heat lost by radiation from the walls 1 of the furnace. The bottom of the crucible 3 is perforated with small holes through which the glass flows and forms fibres which are drawn downwards by a pair of small rollers 8. The rollers are pressed together by springs and can be separated to allow the passage of a bait when starting the drawing operation. They are mounted in a spinning-head 7 which is supported and rotated by three discs 9. Thus the rollers are also rotated in the plane of their axes and they strand the fibres in addition to drawing them. The stranded fibres 10 are collected in a receptacle or can 11 which is pressed into contact with, and is rotated by, the spinning-head 7. The strand 10 tends to coil itself in the can 11 under the action of centrifugal force. By altering the relation between the speed of rotation of the spinning- head 7 and the roller 8, the fibres can be stranded into a cord of circular cross-section or into the form of a flat tape. The stranded thread can also be wound on to a rotating spool if desired.
